Correct Answer: Disodium hydrogen phosphate
Solution : The correct option is Disodium hydrogen phosphate.
The acid with the basicity one is disodium hydrogen phosphate (Na2HPO4), which has one interchangeable hydrogen ion. Because phosphoric acid (H3PO4) has three interchangeable hydrogen ions, it can supply three H+ ions in a chemical process. Sodium dihydrogen phosphate (NaH2PO4) can donate two hydrogen ions, whereas sodium phosphate (Na3PO4) has no hydrogen ion to donate.
